Maybe read into why the decision was made instead of tweeting that ignoramous.Hmmm….I thought Republicans were all for states being able to make decisions.

Although the majority doesn't explain itself, I think it is pretty clear that five Justices didn't think much of a District Court Judge vacating a duly promulgated nationwide regulation, especially without determining the merits of the lawsuit challenging the rule, and especially when the Agency that did the promulgating didn't ask for such an extreme remedy.
Given what goes into federal rule making, it seems uncontroversial that a better course is for rules not to be erased until the merits of doing so have been determined and then reviewed by an Appeals Court.
So, while Justice Kagan and the other three Justices also have a point that there should be a high bar for the Court to use its emergency jurisdiction to step into matters that have not yet reached the Supreme Court on the merits, the District Court's action, and the Ninth Circuit's refusal to step in, may have been an emergency of a different kind.
